1.4 Introduction

Question 1

Distance Formula

Answer 1

Let A = (x1, y1) and B = (x2, y2) be points on a coordinate plane. The distance between A and B is AB = (root sign) (x2-x1)2 + (y2-y1)2

Question 2

Midpoint of a Segment

Answer 2

A point that divides a segment into two congruent segments

Question 3

Midpoint Formula

Answer 3

Let A (x1, y1) and B (x2, y2) be points on a coordinate plane. The midpoint of line AB is (x2 + x1 / 2, y2 + y1 / 2)
